Macro shot of the surface of a bubble. I used a cheap make up ring light which i put around the surface where i created the actual bubble. i tried different ratios of water and detergent, each one giving me different results. i also moved around the actual light and thats how those dark patches came to be.

No digital manipulation aside from a a bit of color saturation

I used a sony a74 with a 135mm f2.8 at F8 with a SS of 1/200 at 100mm canon macro lens with an adapter.
